How much water to add to make a 500 dilution?
To make a 500 dilution, add 1 part of the substance you are diluting to 499 parts of water. For example, if you have 1 mL of the substance, you would add 499 mL of water to make a total volume of 500 mL for the dilution.
What is the molar solution?
When we say that a solution has a given molarity, it tells you how much of a given substance is dissolved into the solution. A 1.0 molar solution has one mole of a substance dissolved into one liter of water.
What does dilution and concentration mean?
Dilute it when there isn't much solute in the solution. So there is a lot of solvent. Concentrated mean there is a lot of solute in the solution.
How much grams of kmno4 to prepare 1000 ppm solution?
To prepare a 1000 ppm (parts per million) solution of KMnO4 (potassium permanganate), you need 1000 mg of KMnO4 per liter of solution. Since 1 gram equals 1000 mg, you would need 1 gram of KMnO4 dissolved in enough water to make a final volume of 1 liter. Therefore, to prepare a 1000 ppm solution, dissolve 1 gram of KMnO4 in 1 liter of water.
How much sodium chloride must be added to one liter of water to make normal saline?
To make normal saline, you would need to add 9 grams of sodium chloride to one liter of water. This is equivalent to approximately 0.9% saline solution.
You want 1 liter of 0.1 M NaCl and you have 4 M stock solution How much of the 4 M solution and how much dH2O will you measure out for this dilution?
To make 1 liter of 0.1 M NaCl solution, you will need 25 ml of the 4 M NaCl stock solution and 975 ml of water. This will give you the desired concentration of 0.1 M NaCl in a total volume of 1 liter.
How much water to add to make a 500 dilution?
To make a 500 dilution, add 1 part of the substance you are diluting to 499 parts of water. For example, if you have 1 mL of the substance, you would add 499 mL of water to make a total volume of 500 mL for the dilution.
How much water must be added to 1 liter of a 5 percent saline solution to get a 2 percent saline solution?
At dilution always true:Volume*concentration = amount of solute (= constant, not changing)So 1 (litre) * 5 (%) => 5
What is the molar solution?
When we say that a solution has a given molarity, it tells you how much of a given substance is dissolved into the solution. A 1.0 molar solution has one mole of a substance dissolved into one liter of water.
How do you prepare 1.5 mol per liter of hcl in solution?
By dilution, but this depends totally on:How much litres you want to have. (suppose V1 Litre)The concentration of the UNdiluted (more concentrated) HCl you have to start with. (suppose M2 mol/L HCl)Then, with V1 * M1 = V2 * M2, you can calculate V2, which is the amount of undiluted HCl solution (in Litre):V2 = [V1 * 1.5] / M2
How much calcium chloride should be added to a liter of water to produce a saturated solution?
This is from the website linked to the left of this answer under Web Links:Solubility in water, g/100 ml at 20°C: 74.5Therefore, in 1 liter, 745.0 grams of CaCl2 will dissolve to make a saturated solution.
What is Molar Solutions?
When we say that a solution has a given molarity, it tells you how much of a given substance is dissolved into the solution. A 1.0 molar solution has one mole of a substance dissolved into one liter of water.
Suppose 1 liter of water with conductivity 10 microS per cm and 1 liter of water with conductivity 20 microS per cm are mixed together then how much will be the conductivity of the net solution?
13,2
A chemist wants to make a 10 solution of fertilizer. how much water and how much of a 30 solution should the chemist mix to get 30 L of a 10 solution?
30 liters of a 10 % solution of fertilizer has .1(30) = 3 liters of fertilizer 1 liter of 30% solution has .3 liter of fertilizer 10 liters of 30% solution has 3 liters of fertilizer so, the chemist needs 10 liters of the 30% solution and 20 liters of water to make 30 liters of a 10% solution.
How much of a 50 percent solution should be added to 1 liter to make a 25 percent solution?
Mix this 50% solution in equal quantities with water(?) to halve it's strength. So use 1 litre of the 50% solution and 1 litre of water of that's what you are diluting it with.
What does dilution and concentration mean?
Dilute it when there isn't much solute in the solution. So there is a lot of solvent. Concentrated mean there is a lot of solute in the solution.
How much sea salt do I add to tap water to make a salt water solution that emulates sea water.?
Seawater has a salinity of arround 3.5 percent. 1 liter is 1000 cubic centimeters needs 35 gram of salt so get this solution.
